To all {whom it may concern Be it known that I, Gmom'uo (Poncaro, a subject of the King of Italy, residing at Perth Amboy, in the county of Middlesex and State of New Jersey, have -invented certain new and useful Improvements in Resilient Tires for Vehicle-'Whekals; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and -to characters of reference marked thereon, which forma part of this specification.

The present invention relates, generally, to improvements in resilient tires for'vehicle wheels; and the invention hasreference, more particularly, to a resilient tire of the paler! matic type provided with a novel construction and arrangement of protecting tread,

together with means for detachably' connccting the pneumatic element of the tire both with the rim of the wheel and with said novel protecting tread.

The invention has for its principal object to provide a pneumatic tire with a novel protecting tread, which is so arranged therewith as to protect the tire from the wear of traction, and also from liability of puncture; and another object of the said invention is to provide a novel means'of associating and connecting said novel tread'hoth with the pneumatic tire or element and with the vehicle wheel itself, all in such a'manner, that in the evcnt'of injury or collapse occurring in said pneumatic tire or element, the same may be detached from both the rim 'ofthe vehicle wheel and from'the novel tread to permit the same to be r'epaireda'nd thenre- I vehicle wheel corhprisi or the old or reous devices and parts, as well as in the deails of the construction of the same, all of Inch will be more fully described in the follow n' specification, and then finally embodle in theclauses of the claims which are appended to and which form an essential part-of this specification.

The invention is clearly illustrated in the accompanying drawings, in which-' Figure 1' is aside elevation illustrating the inner side of a vehicle wheel equiipped with the novel resilient tire and tree therefor, Ina'de according to and embodying the principles ofmy'present invention; and Fig. 2 is a side elevation illustrating a portion of the outer side of the'vehiele wheel equipped with the rim of the vehicle wheel. Fig. 7 is a detail. horizontal section taken on line7-7 in; said Fig. 3' looking downward. Similar characters-of reference are employed in all oithe-hereina'bove described views, to indicate correspondin parts.

'Refe'rrin now to-the said rowing! the reference mean indicx'tesa com lete a hub 2 om which-radiate thespoke'sfi, and 4 indicates the telly which is supggrted at the outer ends of said spokes 3'; cured to said telly 4 isthefixd portion 5 of a clencher rim, the attachable Or-temtWalbl portion of which is indicated by the reference numeral 6. v

The referencev character 7 indicates the outer casing or shoe of an "ordinary pneumatic the, the inner marginal edges of which are provided with the annular ribs or rojections 8 adapted to be engaged by sai clencher-rim members for securin the pneumatic tire to the telly of the ve icle wheel. The said'felly is provided with holding latches or lugs-9, which are turned across said detachable or removable portion holdin relation to hot the fixed portion 5 of sai clcncher-rim and said outer casing or shoe 7 of the neumatic tire which is associated therewit Arrangedwithin said outer casing or shoe 7, in the usual manner, is a pneumaticinner tube 10, adapted to receive and hold air under pressure.

Secured upon the outer surface of said outer casing 01' shoe 7, by means of rivets 11, or an other suitable holding means, is 0. meta '0 band or ring 12, the same being of slightly smaller diameter than the extreme diameter of said outer casing or shoe 7, so that when air under pressure is introduced into the pneumatic tire, the said outer casing or shoe will be forced outwardly so as to tightly hug or embracesaid band or ring 12, which Wlll then appear to be slightly embedded in the outer surface of said outer casingor shoe 7. In order to prevent the fastening or holding rivets 11 from pulling out of or through said. outer casing or shoe 7, the inner ends of the same are securedin anchor plates 13 which are registered upon the inner surface of said outer casing or shoe 7 Secured upon said metallic band or ring 12, andspaced away from one. another at suitable intervals, are a plurality of transversely extending yoke pieces 14. Said yoke-pieces are provided atone end with an outwardly extending lug or arm 15, the samebeing preferably arranged, at right an les tothe mainbody of said yoke-piece. ivotally connected, by means of a suitable -member 16, with the opposite end of sai yoke-pieces 14 are lugs or arms 17, which may be disposed at right angles so as to project outwar ly from the main-body of said yoke-piece, or the same may beturned downward y so as to lie in the plane of said eke-piece, for the purpose subsequent y to be described. Each of said lugs or arms 15 and 17 of said yoke-pieces 14 are provided with suitably positioned holes or perforations 18, which are in alinement with each other when said res tive lugs or arms are both in upright position.

The reference character 19 indicates an outer metallic tire or tread. This tire or tread may be equipped with a resilient surface material 20, made of rubber, leather, or any other desirable or suitable material, and attached to the outer surface of said tire or tread 19 in any suitable manner, but such resilient surface material -is -not essential to the proper function of the novel tire embodymg the principles of my present invention, and the same maywbe'omitted so that the metallic tire, or tread alone provides the traction surface, and infectthe latter condition 1S preferable 101'- me vehlclewlieels of heavy vehicles, such as trucks, omnibus'es,

delivery-wagons, and vehicles of similar character;

Fixed at the under or inner side of said metallic tire or tread 19, so as to form an integral fpart thereof or held'in place b suitable astening means, are pairs of para lel ribs or projections 21 spaced from each other at suitable intervals, or if so desired the same may be made continuous around the inner surface of said metallic tire or tread. Said parallel ribs or projections are provided wit further provided with oppositely facing holes or perforations 23 placed in suitable locations. The free edges of said parallel ribs or projections 21 are further provided with oppositely facing rectangular cut-away pgrtions 24, the same being located in line neath said holes or perforations 23. The reference characters 25 indicate a series of retainin elements, the upper or outer ends of which are preferably bifurcated to provide a pair of arms 26. Each of the arms 26 are turned or bent to rovide forwardly projecting portions 27 he said forwardly p ojecting ortions 27 are in: serted throng the sai pairs of oppositely facing or registered openings 22, so as to extend transversely through said arallel ribs or projections 21 of said meta 'c tire 'or tread 19. When thus arranged a kee rplate 28 is screwed, or otherwise secure to the underside of each forwardly projecting portion 27, so that the same is interposed between said parallel ribs or projections 21, and thus retain said rojecting portions 27 from withdrawal, and thereby pro erly connect said retaining elements 25 with or tread 19. As thus arranged said retaining elements are disposed to extend radially toward the hub of the vehicle wheel. Said retaining elements are all connected together by means of a circular-member 29 to which said retaining elements are bolted.

While I have described and shown said tion providing two arms 26 and projecting since I may effectively usea single arm 26 and projecting portion 27 in place of twoof the same to each retaining element 25'.

portions 27, it must be understood that I do. not limit myself to such an arrangement,

ations, the repaired or new pneumatic tire or element may be again connected and mterloeked with the metallic tire or tread 19.
